This invention relates to a'striker attach-- ment for animal traps as distinguished from closed and the striker being shown in its' the permanent inclusion of 4the striker as a.

part of the animal trapk construction.. p l

The main object is to provide a simple, practical and `convenient striking device Awhich may be easily and quickly* attached to or removed from the frame of -any twinjaw animal trap without in any way disturbing' Vany of the parts of the trap thereby increasing the range of usefulness of the sametrap for animals of diiierent sizes or species and: vavoiding the expense and necessity for purchasing and setting dili'erent types of traps.

One of the specific objects isrto provide the attachment with means whereby it may be'automatically locked in place upon rthe frame of the trap by the simple operation j cient to extend across the adjacentedge. of`

of slidably engaging the attachment with said frame. j

A further object 'isto providev the attachment with means adapted-tocooperate with one of the jaws of the trap when they attachment is placed upon the frame to hold the iv spring actuated striker/against the action of its spring. f

Other objects and uses relating to specific parts ot' the attachment will be brought out in the following description.

In the drawings Figure l is a. top plan of a. twin jaw animal trap with the striker attachment in operative position thereon, the jaws being striking. position. i y

Figure 2 is a. top plan, partly broken away of the same trap, and striker attachment with the jaws and striker in their open positions. l

Figure 3 is an enlarged longitudinal sectional view taken on line 3 3, Figure 2.

Figure t is an enlarged transverse sectional view taken'on line 4 4, Figure 1,.

In order that the invention may' be clearly understood I have-shown an ordinary twin jaw tra-p having its jaws as -wpivotally mounted upon the upturned ends Aof the frame bar -badapted to be held in their open positions by a platform -0- and a detent -eagainst the action of the V- shaped leaf spring jf- The striker attachment comprises a plate .--1- having one end provided with a loop -2- which is open at one side to permit the passage of a portion of the frame bar -b therethrough or rather to the loop to be placed over and upon the 4frame bar #-5- by a lateral sliding movement so that the opposite: sidesof the loop Vwill engage kcorresponding faces of the frame bar to hold said framebar and plate against relative vertical A movement.

` A spring leaf latch -B is secured by a rivet -4- or equivalent fasteningmeans to the upper side of the loop f2; and has its free end provided with a downwardlyl projecting shoulder -5- a distance from i and upon the top face of said frame bar.

The depth of the shoulder -5- is sufliythe frame kbar *ZJ- to cooperate withthe closed side of the loop to holdthe frame bar and attachment against relative lateralV movement.

ed to be placed upon the frame `bar ,-5-

j between `the vcenter cross baras -band one of the upturned ends of the bar opposite the leaf spring the length of displacement of the attachment'lengthwise of the bar as limited vby thecross bar -b-jandthe upturned end adjacent the attachment.

In placing the attachment upon the frame Vbar the loop is simply drawn laterally across vsaid loop being sufficientto prevent undue f In removing the attachment it is simply necessary to spring the latch upwardly out of engagement with the adjacent end of the bar -b and then to slide the loop laterally from the bar.

The other end of the plate -l extends some distance beyondthe loop -2- and adjacent end of the frame bar *Z9-.- and is provided with an upturned apertured end ,-6- to which is pivote'd one end of a detent -7 having its other end adapted to be moved to a position directly over the loop for engagement with the lower face of one of the jaws -a-- when said jaws are vopened or set.

The intermediate portion of the plate -1- is provided with upturned apertured ears -8- carrying a pivotalbolt or pin -9- upon which is mounted the ends of a U-shaped striker bar of sullicient length tov vextend beyond the jaws -aand s the upper leaf of the spring to engage when released and i actuated by its operating springe-lle.' t

Ino'the 1 words, the striker bar L10- 'is pivoted to' the'plate' -1 toA 'swing about an axis atright angles to the .axes of the fjaws #cl-'4er 4from a position at one end ol' the traine bar --btoa closed posi-tion at the opposite endl of said bar and across the loop 2fanfd'is provided with a laterally projecting lng' '-l0"- which, when the striker is opened vassumes a position between the pivot e9-L and 'fnlcri'inr as -7- of the detent and adapted to be 'engagedby said detent to holdthe striker in its open 'posi'- tion against the aiction of the spring #llepivotal 'pin --9-V and has "one end ei'rgag'ed with the, plate `--land its other lend engaged with one of 'the arms of the 'U-shaped striker'b'ar l0-"- 'as shown in Figure Q son-Ie dist-ance lfrom the pivotal pin iQ-e.

` are locked Ain their open positions.

lUnder-these conditions the closing action of the striker bar -10- is controlled by the closing' action of the jaws so that when the 'aws of fthe trap are released the detent -fwill 'alsoabe released to perniit the operation of the striker bar by its operating spring 11- thereby causing the striker bar to straddle the closed jaws -a' and to extend sii-'Hic-ient distance beyond the vsaline to engage the upper leaf off the jaw actuating spring -fwhich serves to liniit'the closerino` n'iovernfent of 'said striker bar as indi-v cated by dotted lines in Figure V3. v
